Tcl, short for Tool Command Language, is a scripting language created by John Ousterhout at the University of California, Berkeley. He wanted a simple language that could be embedded in applications to control them, so he designed one with a very regular syntax in which everything is a command and the data is stored as strings. It became popular with Tk, a toolkit for creating graphical user interfaces, which is sold together as Tcl/Tk, and the combination was used in many cross-platform applications. Tcl is used for testing and automation, and by the Expect tool for controlling interactive programmes. It also influenced other languages and has been used for decades in electronic design and networking equipment.
